Inheritance diagram for PoDoFo::StreamDevice:

Protected Member Functions
	StreamDevice (DeviceAccess access)

void	resetBuffers () override
	NOTE: It just forwards to InputStreamDevice, disambiguating the InputStreamDevice/OutputStreamDevice inheritance.

Protected Member Functions inherited from PoDoFo::InputStreamDevice
	InputStreamDevice (bool init)

virtual bool	peek (char &ch) const =0
	Peek at next char in stream.

void	checkRead () const override
	Optional checks before reading By default does nothing.

void	resetBuffers () override

void	enableReadWindow (const char head, const char tail)
	Enable the inline read window over the supplied memory region.

void	disableReadWindow ()
	Disarm the read window, handing the logical position back to the device.

Protected Member Functions inherited from PoDoFo::InputStream
virtual size_t	readBuffer (char *buffer, size_t size, bool &eof)=0
	Read a buffer from the stream.

virtual bool	readChar (char &ch)
	Read the next char in stream.

Static Protected Member Functions
static size_t	SeekPosition (size_t curpos, size_t devlen, ssize_t offset, SeekDirection direction)

Static Protected Member Functions inherited from PoDoFo::InputStream
static size_t	ReadBuffer (InputStream &stream, char *buffer, size_t size, bool &eof)
	Read from another stream, to be used by decorator streams on their source.

static bool	ReadChar (InputStream &stream, char &ch)

Additional Inherited Members
Public Member Functions inherited from PoDoFo::InputStreamDevice

size_t	Read (char *buffer, size_t size, bool &eof)
	Read data from the device.

char	ReadChar ()
	Get next char from stream.

bool	Read (char &ch)
	Get next char from stream.

void	CopyTo (OutputStream &stream)
	Copy this stream to another.

	Copy this stream to another.

Protected Attributes inherited from PoDoFo::InputStream
const char *	m_head
	Inline read window over memory that already holds the bytes at the current logical position.

const char *	m_tail

Detailed Description

This class provides an output device which operates either on a file or on a buffer in memory.

Additionally it can count the bytes written to the device.

This class is suitable for inheritance to provide output devices of your own. Just override the required virtual methods.
